  • Patent number: 11091660
    Abstract: The present invention relates to the use of a thermosetting polymeric powder composition in a 3D printing process to produce a 3D duroplast, wherein the composition comprises at least one curable polymeric binder material and at least one thermoplast having a Tg and/or Mp below the temperature provided in a pass of the printing process and wherein during each pass of the printing process said polymeric binder material is at least partially cured within the layer thus formed and also at least partially crosslinked with the previous layer. The invention furthermore relates to a 3D printing process using such a thermosetting polymeric powder composition and a 3D-printing product obtained when using such a thermosetting polymeric powder composition.

  • Patent number: 10889722
    Abstract: The present invention relates to a powder coating formulation, comprising at least one partially crystalline thermoplastic unsaturated polyester (A), at least one thermoplastic allyl prepolymer (B) which is copolymerizable with said polyester, and a thermal initiation system (C), including at least one thermal initiator, wherein the allyl prepolymer (B) has a weight average molar mass greater than 5000 g/mol, preferably greater than 10000 g/mol, and particularly preferably greater than 20000 g/mol, and/or has a viscosity of 30 mPas to 200 mPas, preferably of between 40 mPas and 170 mPas, particularly preferably of between 50 mPas and 150 mPas, and wherein the unsaturated polyester (A) has a melting point of between 90 and 120° C., preferably of 90-110° C., particularly preferably of 90-105° C., and still more preferably of 90-100° C.

  • Patent number: 10780630
    Abstract: The present invention relates to the use of a thermosetting polymeric powder composition in a Selective Laser Sintering process to produce a 3D duroplast, wherein the composition comprises at least one curable polymeric binder material and wherein during each pass of the SLS process said polymeric binder material is at least partially cured within the layer thus formed and also at least partially crosslinked with the previous layer. The invention furthermore relates to a SLS process using such a thermosetting polymeric powder composition and a 3D-printing product obtained when using such a thermosetting polymeric powder composition.

  • Publication number: 20200062952
    Abstract: The present invention relates to the use of a thermosetting polymeric powder composition in a 3D dry printing process to produce a 3D duroplast object, the composition comprising at least one curable polymeric binder material with free functional groups, wherein during the 3D dry printing process the formed object is only partially cured to a curing degree of below 90%, preferably below 60%, most preferably between 35% and 60%, and the printing process is being followed by a post treatment comprising a heat treatment step to fully cure the printed object into a 3D duroplast object.
